Personally, Rah, neither does Sony.
Your idea of an adult story and my idea seem pretty different.
Uncharted features a man that kills thousands and people are crying about the dude who is basically Indiana Jones. We watched Indiana Jones in daycare at elementary school. Personally, I find these people have a limited definition of an adult story.
To me an adult story is something that has actual adult content, depth, themes, and layers. God of War is not an adult story. Uncharted is not an adult story. Haven’t played but I doubt The Last Of Us is an adult story either.
Actual adult stories I can think of in games: Silent Hill 1 and especially 2, Planescape: Torment, Fallout games that aren’t 3 (haven’t played 4), Tactics Ogre, Max Payne 2, Vampire: The Masquerade - Bloodlines, Valkyrie Profile 1, I think that’s it. That’s not to say these are the only good stories in games I’ve played. My favorite game story is probably within the Suikoden franchise and I’m not sure I’d call it adult. I love Final Fantasy VI’s story but it’s clearly not an adult story. Neither is Final fantasy X’s or even VII’s. Final Fantasy games in particular are aimed specifically at teenagers. I got into FF when I was 12 so the idea that it’s adult is laughable to me. MGS is basically a suped up GI Joe.
Few games have adult stories. What an adult story? Lolita, which is sitting on my bookshelf is. Barry Lyndon. The Shining. Jacob’s Ladder. Perfect Blue. Grave of the Fireflies. The Color Purple. Jane Austen shit. Wuthering Heights. Idk, I’m spitballing here.
One thing you learn quickly when developing taste in your late teens and through your 20’s is that nerd shit != adult shit, with few exceptions.
You talk about Nintendo not making adult stories yet funnily none of the AAA story based games I’ve played in the past decade have matched the literary content of Majora’s Mask.
So there’s that.
